First introduce the several nouns involved in this application:

Android operating system: A Linux-based free and open source operating system produced by Google Inc. of the United States, mainly used in mobile devices.

Application: Referred to as an application, in an Android operating system, an application usually includes at least one program component. There are four types of program components: Activity: Activity component, Service component, Content Provider component, and Broadcast Receiver component.

Active component: A component of the Android application that is responsible for interacting with the user, providing a visual user interface for Android applications. An Android app can include zero to more active components.

Service component: A component of an Android application that runs in the background and does not provide a user interface. Usually used to process data. An Android app can include zero to more service components.

Content Provider Component: A component of an Android application that provides data for other applications or other components in the current application, such as ringtones, wallpapers, phone books, and so on. It encapsulates data in a variety of formats and provides it to other applications or components in a standard form.

Broadcast Receiver Component: A message used to receive and respond to broadcasts by the operating system. It can receive messages of interest to itself (or pre-defined messages of a certain message type) and then process or forward them to other components in the current application.

Intent (English: Intent) message: A message in the Android application that communicates between various program components. Each program component can be a different component in the same application or a different component in a different application. . The Intent message is responsible for the action of one operation in the application, The action involves data and additional data for description. The Android operating system is responsible for finding the corresponding program component according to the description of the Intent message, passing the Intent message to the called program component, and completing the calling of the program component. There are two types of Intent messages: explicit Intent messages and implicit Intent messages.

Explicit Intent Message: An Intent message that explicitly indicates the name of the target program component is called an explicit Intent message. For example, the A program component needs to send an Intent message of “call 18688888888”. If the A program component wants the B program component to respond to the Intent message, the A program component specifies the target program component in the Intent message to be the B program component. After the Android operating system receives the Intent message, the Intent message is handed over to the B program component for processing.

Implicit Intent Message: For an Intent message that does not explicitly indicate the name of the target program component, it is called an implicit Intent message. For example, the A component needs to send an Intent message "call 18688888888". If the A component does not know which program component should respond to the Intent message, then the A component can not specify the target program component in the Intent message, then the Android operation After receiving the Intent message, the system will check the type of the Intent message that is pre-registered by each program component. If the B program component monitors the Intent message about the phone call, the Android operating system will hand over the Intent message. B program component processing. Alternatively, the Android operating system can broadcast the Intent message, which is received and processed by a broadcast receiver component interested in an Intent message regarding the phone call.

Please refer to FIG. 4A , which is a flowchart of a method for displaying a button provided by an embodiment of the present application. This embodiment is exemplified by applying the key display method to the terminal shown in FIG. 1 or 2. The method includes:

Step 401: Display a first user interface and a navigation bar, where the navigation bar includes a target virtual button;

Alternatively, the target application is a camera application, or the target application is an instant communication program including a shooting function.

Step 404: Display a second user interface of the target application, and switch the target virtual button in the navigation bar to a shooting button.

After starting the target application, the terminal displays all or part of the interface area of the first user interface as the second user interface of the target application. Optionally, the second user interface is a shooting interface or a camera interface.

The terminal also switches the target virtual button in the navigation bar to the capture button. The capture button is a control that triggers the target application to take a photo or video. The capture button can be a virtual button instead of a physical button.

In the example shown in FIG. 4B, the terminal switches the home button 42 to the shooting button 44.

In summary, the button display method provided by the embodiment is configured to switch the target virtual button in the navigation bar to a shooting button after the target application is started, so that the target virtual button that is easily misunderstood is not in the shooting process. The display is further displayed, so that the virtual button is not accidentally touched, which solves the problem that the user can easily touch the home button on the navigation bar when the virtual shooting button is clicked, and the effect of reducing the chance of accidental shooting during shooting is achieved.

Please refer to FIG. 5A , which shows a flowchart of a button display method provided by another exemplary embodiment of the present application. This embodiment is exemplified by applying the key display method to the terminal shown in FIG. 1 or 2. The method includes:

Step 501: Display a first user interface and a navigation bar, where the navigation bar includes a target virtual button;

The first user interface may be a main interface or a lock screen interface provided by the operating system. As shown in FIG. 5B, the first user interface 40 occupies a mid-upper display area on the touch display screen.

The navigation bar can be a control provided by the operating system for displaying at least one virtual button. The navigation bar can be displayed in the bottom display area of the touch display, also called the bottom navigation bar (Bottom Navigation Bar). At least one of the virtual buttons displayed on the navigation bar can be a system level virtual button. As shown in FIG. 5B, at least one of the virtual buttons includes, but is not limited to, a return key 41, a home button (also referred to as a Home button) 42, and a menu button 43. Optionally, the layer overlay of the navigation bar is displayed on the layer of the first user interface.

The target virtual button is a virtual button that is easily touched by mistake, and the target virtual button may be all or part of a plurality of virtual buttons displayed on the navigation bar. For example, the target virtual button is the home button 42; for example, the target virtual button is the return button 41, the home button 42 and the menu button 43.

Step 502: Receive a first operation signal.

Step 503, starting a target application according to the first operation signal;

After receiving the first operation signal, the terminal starts the target application. The target application is an application that includes a shooting function.

Step 504: Display a second user interface of the target application, and switch the target virtual button in the navigation bar to a shooting button.

Optionally, after the target application is started, the terminal displays all or part of the interface area of the first user interface as the second user interface of the target application. When the target application is a camera application, it is possible to switch directly from the first user interface to the second user interface.

Optionally, after the target application is started, if the foreground running interface of the target application is the interface of the shooting function, the target virtual button in the navigation bar is switched to the shooting button. For example, when the target application is another application with a shooting function, the first user interface can be switched to be displayed as another interface (such as the main interface of the program) when the target application is started, and then switched to the first time after the user's operation. Two user interface.

Optionally, the terminal cancels display of all or part of the interface area of the first user interface, and replaces the display as the second user interface on the interface area. Optionally, the second user interface is a shooting interface or a camera interface. At this time, the second user interface displays control elements related to shooting, including but not limited to: shooting finder frame, flash control, sensitivity control, color temperature control, delay control, shooting mode selection control, shooting At least one of the image viewing controls.

The target virtual button can be all or part of a virtual button on the navigation bar. Optionally, the target virtual button is a centrally located virtual button on the navigation bar, such as a home button. The target virtual button may also be a menu key or a return key, which is not limited in this embodiment.

The terminal also switches the target virtual button in the navigation bar to the capture button.

In a possible implementation manner, the terminal cancels the display of the target virtual button in the navigation bar, and replaces the display as a shooting button. The shooting button is a control for triggering shooting or shooting. The capture button can be a virtual button instead of a physical button.

In another possible implementation manner, the terminal keeps the display state of the target virtual button in the navigation bar unchanged, but switches the code logic used to respond to the target virtual button to switch to code logic for responding to the shooting button. . That is, although the display state of the target virtual button does not change, when the user clicks the target virtual button, the shooting function is triggered instead of the function of the target virtual button.

In the example shown in FIG. 5B, the terminal switches the home button 42 to the shooting button 44. The photographing button 44 occupies the original display position of the home button 42, and the button shape of the photographing button 44 is different from the button shape of the home button 42.

Step 505: Receive a touch signal triggered on a shooting button;

When the user needs to shoot, the user clicks the shooting button in a touch form. After receiving the click operation, the touch display screen on the terminal generates a touch signal according to the click operation, and reports the touch signal to the CPU.

Step 506, controlling the target application to perform shooting according to the touch signal;

The CPU in the terminal controls the target application to take a picture or video according to the touch signal.

Step 507, receiving a second operation signal;

The second operational signal is a signal used to exit the target application. The second operation signal may be a signal generated after the operation object clicks the return key, that is, the terminal receives the second operation signal acting on the return key. The second operation signal may also be a signal generated by the operation object sliding down the second user interface, or may be a signal generated by pressing a predetermined physical button on the terminal, which is not limited in this embodiment.

Optionally, when the target virtual button is the home button, the second operation signal is a signal generated by the operation object clicking the return button; when the target virtual button is the return button, the second operation signal is generated by the operation object clicking the home button Signal; when the target virtual button is a menu button, the second operation signal is a signal generated by the operation object clicking the back button or the home button.

Step 508, exiting the target application according to the second operation signal;

After receiving the second operation signal, the terminal exits the target application. Optionally, the terminal displays the second user interface recovery of the target application as the first user interface.

In step 509, the shooting button in the navigation bar is restored to the target virtual button.

The terminal restores the shooting button in the navigation bar to the target virtual button.

Optionally, when the target virtual button is the home button, the shooting button in the navigation bar is restored as the home button.
